driver
Adaptive Cruise Control will be deactivatedand put in standby mode if any of the follow-ing occurs:
The brakes are applied.
The gear selector is moved to
N.
The vehicle is driven faster than the setspeed for more than 1 minute.
Temporarily increasing speed using the accel-erator pedal, e.g. when passing another vehi-cle, will not affect the setting. The vehicle willreturn to the set speed when the acceleratorpedal is released.
WARNING
If Adaptive Cruise Control is in standby mode, the driver must intervene andregulate both speed and distance tothe vehicle ahead.
If the vehicle comes too close to a vehi-cle ahead when Adaptive Cruise Con-trol is in standby mode, the driver canbe warned of the short distance by the Distance Alert

Setting time interval to the vehicle ahead The time interval to the vehicle ahead can be set for the functions Adaptive Cruise Control *,
Pilot Assist * and Distance Alert *.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, thelonger the time interval. Onebar represents an interval of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasona-ble distance.
NOTE
When the symbol in the instrument panel shows two vehicles, Adaptive Cruise Con-trol is following the vehicle ahead at a pre-set time interval. When only one vehicle is shown, there is no vehicle ahead within a reasonable dis-tance.
Controls for setting a time interval.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the current time interval. In order to help your vehicle follow the vehicle ahead as smoothly and comfortably as possi-ble, Adaptive Cruise Control allows the timeinterval to vary noticeably in certain situations.At low speeds, when the distance to the vehi-cle ahead is short, Adaptive Cruise Controlincreases the time interval slightly.
NOTE
The greater the vehicles' speed, the greater the distance between them fora set time interval.
Only use the time intervals permittedby local traffic regulations.
If driver support does not seem torespond with a speed increase whenactivated, it may be because the timeinterval to the vehicle ahead is shorterthan the set time interval.
WARNING
Only use a time interval suitable for the current traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.
